These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Complete Monster: Wayne Callison probably qualifies, what with the whole torturing women to death, hiding their bodies underneath his younger brother's (whom he goaded into raping a girl at the tender age of 15) deck. He then threatens Stark's daughter during questioning just to enrage the guyto the point of attacking him, then tries to get him thrown off the case for it. When that doesn't work, he drives his one escaped victim to suicide and uses a loophole from that to become a temporary Karma Houdini. And that was just in his first episode.
